Light: Morning sun with afternoon shade in Phoenix; bright filtered light also works. Acclimate gradually to direct sun to prevent scorching.
Water: Low water; water deeply, then let the root zone dry completely. Reduce watering sharply in winter, especially during cold weather.
Soil: Very well-drained, gritty or gravelly soil. For containers, use cactus mix amended with pumice or coarse mineral grit.
Mature size: Typically 10–15 feet tall and 4–6 feet wide in the ground under favorable conditions; usually smaller in containers.
Bloom: Mature plants may bloom from late spring through summer; flowering is less reliable on young or container-grown specimens.
Evergreen / deciduous: Evergreen succulent cactus.
Growth rate: Moderate to fast during warm weather with suitable light, water, and root space.
